Safety closure cap for a container

Abstract

A container closure having a lower closure element and a closure cap disposed on a primary spout formed by the lower closure element. The closure element has a cover and, formed thereon, a cap casing with at least one shoulder. The lower closure element has at least one counter-element which cooperates with the shoulder to form a snap-on connection. The closure cap includes a force introduction member for introducing a pulling or pushing force into the lower closure element by a force transfer member. A transition piece through which the lower closure element maintains the counter-element at a distance from the line of force of the force introduced into the lower closure element is also provided. The counter-element, when the force is applied, is elastically deflectable by the transition piece in a direction facing away from the cap casing of the closure cap.
